[Live-devel] Convert A camera stream without saving it in a file, how to directly take an rtsp stream convert it and send it to a client without big delay of conversion

Yes.  The easiest way to do this is to modify the “testH264VideoToTransportStream.cpp” code to:
1/ Change inputFileName from “in.264” to “stdin”, and
2/ Change outputFileName from “out.ts” to “stdout”.

Then modify the “testMPEG2TransportStreamer.cpp” code to:
3/ Change inputFileName from “test.ts” to “stdin”, and 
4/ Change destinationAddressStr and rtpPortNum from built-in constants to command-line arguments.

Then run, for each camera:
	openRTSP -v camera-rtsp-url | your-modified-testH264VideoToTransportStream | your-modified-testMPEG2TransportStreamer client-rtp-address client-rtp-port &
I.e., for each camera, you run “openRTSP” on it, piping its H.264 video output to (your modified) “testH264VideoToTransportStream”, then piping the Transport Stream output of that to (your modified) “testMPEG2TransportStreamer”.
